Want an enterprise router for your network at a fraction of the cost of a Cisco router? You can connect your offices together, remotely access files, run enterprise Wi-Fi encryption, and more. Eric Geier, author of Wi-Fi Hotspots: Setting Up Public Wireless Internet Access, concludes his two-part tutorial on getting a RouterOS machine up and running on a spare PC.

Enter the DHCP address range. You'll probably want to change it to something like 192.168.1.100-192.168.1.199, so you can use the first 100 addresses for the router and any access points (APs) or servers loaded with static IPs. Then you can better distinguish between the addresses for the APs/servers and the end users.

Specify the DNS server used by your ISP and click Next. It might be auto detected; otherwise, you might just use OpenDNSs: 208.67.222.222 and 208.67.220.220.

The default lease time (every three days) is probably fine; however, if you prefer something else, make the change and click Next.
